This effect is highly anticipated by patients - the beneficiaries of therapy. In order to increase the dynamics of the osseointegration process in intraosseous dental implants, there is ongoing research on the type of material from which the implants are made, their design features, surface topography, as well as the formation of layered structures and coating applications. The use of growth factors and other biologically active factors affects the increase in the dynamics of osseointegration strength in intraosseous dental implants. The possibility of introducing these factors into the direct surroundings of the implant during healing is important. The entire implant or porous section of the implant according to the invention can advantageously be produced by 3D printing through selective melting/sintering of biocompatible metallic, ceramic or metallic-ceramic composite powders with laser or electron beam.

A method of nanocrystalline structure formation in bearing steel, characterised in that in the first stage, an element made of a commercial bearing steel with the following chemical composition (by wt. %): carbon: 0.93+1.10, silicon: 0.4÷0.75, manganese: 0.95÷1.25, chromium: 1.30+1.65, phosphorus up to 0.027, sulphur up to 0.02, nickel up to 0.3, copper up to 0.25 and unavoidable impurities, is heated to an austenitising temperature in the range of 900÷940°C and held in this temperature for 10÷45 minutes. Then, the steel is cooled to the isothermal holding temperature in the range of 300÷350°C, higher than the martensite start temperature but lower than the bainite start temperature. The cooling rate from the temperature of austenitising should be high enough to avoid the pearlite reaction, i.e. a rate higher than the critical rate preventing the occurrence of diffusive transformations. In the case of this steel, the cooling rate should be 8°C/s or higher, depending on the size of the element and the chemical composition of the steel. The subsequent annealing at the isothermal holding temperature for a period of 5-8 hours is used in order to complete the bainitic reaction, and then the material is cooled down until the room temperature is reached.

In more detail: the invention represents the method for obtaining the tissue engineered product in cell culture conditions in vitro on degradable material. The product consists almost entirely of natural components, which are produced by cells seeded on a resorbable material. When the cells come from the donor who is also the recipient of the graft, the product is composed of his/her own biological material. Such composition ensures immunological compatibility, which does not occur in the case of biological material obtained from an incompatible donor or when the biological material is of animal origin, which is often the case in current clinical practice.
